Knockout Riches

Knockout Riches by PG Soft takes boxing as its setting and turns the sport into a slot mechanic: the Stacking Symbols Feature builds values above three central reels over multiple rounds, then fires them all simultaneously when the sequence ends. The 5x3 base layout expands dynamically, reels 2, 3, and 4 can grow from 4 to 20 rows, and the game can reach up to 8,000 ways to win. With a 96.75% RTP, high volatility, a 10,000x max win, and a release date of April 2025, it is one of PG Soft's more structurally adventurous recent titles. Playable on desktop and mobile at Wild.io.

What is Knockout Riches?

Knockout Riches is a 5x3 (expanding) video slot from PG Soft with a 96.75% RTP, high volatility, and a top win of 10,000x your bet. Its standout mechanic is the Stacking Symbols Feature, where values accumulate above reels 2, 3, and 4 across multiple rounds before a final merged-reel payout fires all stacked values at once.

The reel structure is unusual: reels 1 and 5 are fixed at 1 to 3 rows, while reels 2, 3, and 4 grow dynamically from 4 to 20 rows. Up to 8,000 ways to win activate as the center reels expand. PG Soft built the game around Ruby, a boxer styled as the 'Flaming Rose,' giving the base-game and bonus mechanics a sporting-competition narrative frame.

Knockout Riches Slot Theme & Graphics

Knockout Riches uses a boxing gym and arena aesthetic: bright ring lights, championship belts in the background, and a color scheme built around gold, black, and the red of Ruby's 'Flaming Rose' boxing gear. The character Ruby is stylized in PG Soft's anime-influenced art direction, confident posture, distinctive braided hair, fingerless gloves, and appears on the reels as the highest-value premium symbol.

The Stacking Symbols mechanic has its own visual language: the value counters above the central reels display clearly during the multi-round build phase, and the final merge sequence when reels 1 and 5 collapse into a single symbol uses a knockout animation that ties the mechanic back to the boxing theme. On mobile the expanding center reels are handled by scaling the grid vertically, which PG Soft implements cleanly within the game's standard aspect ratio.

Knockout Riches Slot Symbols & Paytables

Knockout Riches keeps its symbol roster tight, the premium set is character and sports-equipment focused, while the low-value tier uses standard card suits with a gym aesthetic.

Low Value Symbols

The low-value symbols are card suit icons treated with the game's gold-and-black visual scheme. They appear across all five reels and are the most common outcome on most spins. During the Stacking Symbols Feature, low-value symbols landing on reels 2, 3, or 4 still contribute to the stacking counters above those reels, making even routine spins part of the feature's value-building mechanism.

High Value Symbols

Ruby herself is the top-paying regular symbol, appearing on all five reels including the fixed outer reels 1 and 5. Supporting premium symbols include boxing-themed equipment and championship iconography. Stacked premium symbols on reels 2, 3, and 4 are the target state in the Stacking Symbols Feature: a merged-reel board where all positions on the three center reels show a stacked premium symbol across 4 to 20 rows, combined with up to 8,000 ways to win, is where the 10,000x maximum win originates.

Special Symbols

The Wild substitutes for all regular paying symbols. The Scatter triggers the Free Spins feature when two land on the same spin. The defining functional symbol is the stacking counter above reels 2, 3, and 4, not a symbol in the traditional sense but a displayed value that tracks accumulated wins during each Stacking Symbols round. When the merge fires at the end of a round (base game or free spins), these counter values determine how tall the stacked symbol columns are, directly affecting the total combined win.

Knockout Riches Bonus Feature & Special Features

Stacking Symbols Feature

The Stacking Symbols Feature triggers during any spin when three or more consecutive rounds are activated. Each round, winning symbols that land on the central reels 2, 3, and 4 increment the value counters displayed above those reels. The center reels can grow from their base 4 rows up to a maximum of 20 rows as values accumulate, increasing the total ways to win progressively. When the sequence concludes, reels 1 and 5, the fixed outer columns, merge together into a single randomly selected symbol. Reels 2, 3, and 4 then fill completely with stacked versions of that same symbol, using the full height that has built up over the stacking rounds, and the resulting combination pays out as one combined win. The full combined payout of a max-height board with a merged premium outer-reel symbol is the mechanism behind the 10,000x ceiling.

Free Spins

The Free Spins round activates when two Scatter symbols land on the same spin, awarding 5 free spins. The feature operates on the same Stacking Symbols mechanic as the base game but in a dedicated mode: winning symbols on reels 2, 3, and 4 during each free spin boost the value counters above those reels, and when the final free spin concludes the merge sequence fires. Reels 1 and 5 collapse into a single symbol, and reels 2-4 fill with stacked versions of that symbol to the full height of their accumulated counters. Because the free spins version runs all five spins before the merge fires, the center reel values have five full rounds of builds before paying out rather than the variable number of rounds in the base game. This structure makes the free spins merge payout generally higher than a typical base-game Stacking Symbols resolution, which is where the feature's value is concentrated.
